Find my band size
No tape measure? A photo is enough. As an image has no scale, we use an object of known size — a bank card or your Apple Watch — as a ruler to estimate your wrist size and recommend the right size.
- 1
Take a photo
Your wrist with a bank card laid on it (or your Apple Watch) as a size reference.
- 2
Place the two markers
The blue line on the card (85.6 mm), the orange one across your wrist.

Get your size
We convert it into a circumference and recommend the S/M/L size suited to your band.
Take a photo of your wrist with a bank card laid flat against it (edge clearly visible). A card is exactly 85.6 mm long — that's our ruler.
Load a photo, then place the blue line on the reference and the orange one across your wrist.
| Size | Wrist circumference |
|---|---|
| XS | 145 – 165 mm |
| S | 165 – 175 mm |
| M | 175 – 185 mm |
| L | 185 – 205 mm |
Indicative estimate (± ~1 cm). If in doubt, measure your wrist with a tape measure and compare with the table above.
Which case size should you choose on the product page?
There are only two fittings. Small: cases of 38, 40 and 41 mm (Series 1 to 9, SE) and 42 mm on Series 10 and 11. Large: 42 mm on Series 1 to 3, 44, 45 and 46 mm, and 49 mm (Ultra). The 42 mm case exists in both families: your watch model decides.
When the product page offers the size for your model, choose it; otherwise, choose the one given after “otherwise”.
